Box 37012, MRC 168, Washington, DC 20013-7012, U.S.A. (e-mail: norman.woodley@ars.usda.gov) Abstract. — Jwinella baonico, n. sp., (Diptera: Tachinidae) is described and illustrated from the Sierra de Baoruco, Dominican Republic. A key to the genera of Tachinini from the Caribbean is presented. Two new generic synonyms are proposed: Hystriciella Townsend, 1915 and Parajwinia Townsend, 1928 both = JurineUa Brauer & Bergenstamm, 1889, resulting in JurineUa pilosa (Drury), new combination and JurineUa obesa (Townsend), new combination. Key Words: Diptera, Tachinidae, Tachinini, JurineUa, Caribbean, taxonomy JurineUa Brauer & Bergenstamm is a New World genus of Tachinini that ranges from southwestern United States to southern Brazil and northern Argen- tina. All of the described species are included in Guimaraes (1971) who listed 53 species in JurineUa, and one each in the genera HystricieUa Townsend and Parajwinia Townsend, which I consider to be congeneric. During collecting in the Dominican Republic I obtained speci- mens of a striking new species that is described herein (my material deposited at the Department of Entomology, Smithsonian Institution, Washington, DC, cited below as USNM). Additional specimens were made available from material collected during several expedi- tions by colleagues from the Carnegie Museum of Natural History, Pittsburgh, PA (cited below as CMNH). Paratypes are also deposited at the Canadian National Collection, Agriculture Ca- nada, Ottawa (cited below as CNC). Members of the tribe Tachinini are moderate to large tachinids that have the prosternum bare, the first postsutural supra-alar bristle at least as long and stout as the first postsutural dorsocentral bristle, and the hind margin of the hind coxa setose, usually over the entire hind margin (but if sparse, present at least on the posterolateral corner). Tachinines are a very diverse tribe in Central and South America, particularly at middle and high elevations, that includes several hundred species. However, the fauna of the Caribbean islands is surprisingly depau- perate, with fewer than a dozen recorded species. This undoubtedly reflects lack of collection to some extent, but in my experience in the Dominican Republic tachinines are truly scarce. Since there are a small number of Caribbean genera and most species in the region are poorly known, it seems worthwhile to present a generic key at this time to facilitate their identification. I have included the VOLUME 109, NUMBER 4 857 islands from which the genera are known based on hterature records and material present in the USNM collection. In all likelihood, some of the genera will be found on additional islands. Taxa from essentially continental islands, especially Trinidad, are not included. Adejeania armata (Wiedemann) was described from a specimen supposedly from Cuba, but this is believed to be erroneously labeled (D. M. Wood, personal communication, cited in Woodley 1993) and no further Adejeania Townsend have been seen from the Caribbean, so the genus is excluded from the key.

Verdecia, C. Young, C. Nunez, W. Zanol (CMNH). Etymology. — The species name, a noun in apposition, is from Sierra de Baoruco, the mountain range from which all known specimens have been collected. Remarks. — Jurinella baoruco is one of the minority species in the genus that has a reddish-brown abdomen. Its general appearance resembles that of Dumerillia rubida Robineau-Desvoidy from Brazil. Dumerilla Robineau-Desvoidy is a mono- typic genus that differs little from Jur- inella, mainly in having smaller patches of discal setae on abdominal tergites 3 and 4, and males which have proclinate orbital setae. It is quite possible that Jurinella will be synonymized with Du- merillia when the generic concepts within this group of tachinine genera can be studied in detail. Jurinella baoruco differs from other described Caribbean species of this genus by having the paler coloration noted above. Both Jurinella pilosa (Drury) and /. epileuca (Walker) have darker abdo- mens and legs, dark brown to black. I have seen a single specimen (CMNH) of Jurinella from the Sierra de Martin Garcia, Dominican Republic, that re- sembles /. baoruco, but it differs by being notably smaller and having more uni- formly pale hairs on the thoracic scutum. It likely represents an additional unde- scribed species. Jurinella baoruco has to date only been collected from the Sierra de Baoruco, formed when the southern paleo-island collided with the northern paleo-island to form modern Hispaniola (Keith et al. 2003 and references therein). Parade- jeania xenisnia Woodley (1993) was also originally known from the Sierra de Baoruco, but I have recently collected specimens near La Cienaga in the Cor- dillera Central, La Vega Province. It seems likely that /. baoruco will eventu- ally be found to have a wider distribution since these insects are strong fliers. The males of J. baoruco I collected near Los Arroyos in 1985 were frequent- ing flowers on roadside shrubs 2-3 me- ters above the ground. Acknowledgments I am very grateful to Chen Young of the Carnegie Museum for loaning mate- rial in his care. Some of the specimens from the Carnegie were obtained during a project funded by National Science Foundation grant DEB-0206520 of the Biotic Surveys and Inventory Program. I am also grateful to Nigel Wyatt of The Natural History Museum, London, for excellent notes he sent on the type of /. epileuca (Walker).
